Thread: Subsonic .223rem

Hi Guys bought some Belmont subsonic .223 [55 grain x 4.10 grain T/Boss
these worked well in the Howa mini 1:8 twist .Also reloaded my own to play around with
last rabbit i shot was@ 80 m slightly down hill with my load . It was very quiet [a lot better than the supp. 22lr ] as i have fitted a very good can on the end of the barrel
I think the flat base fly better for me .But i really need to get busy and start reloading these again

Thanks guys. Sounds like a flat base in the faster twist may be worth a crack.

Use @ your own risk i used Trail Boss
H&N RN 55 grain x 4.5 T/B fast with an echo so was doing just above sub speed
Varmit SP 70 grain x 5.5 grain subsonic poi=poa
it really depends on your barrel and what it likes but in mine using more than 6 grain of powder it starts to get louder
was interested in learning how a subsonic .223 works compared to a 2lr /22 magnum /22 Hornet and so on
just add more powder or use a different type to get the result you seek
Safe loading Cheers

55g projectile and 4g trail boss works for me in the 223

But mostly I carry a .22rf with subs and dial to 200 yrds (70mm group @200)

And a .223, 60g nbt@3100

While one rifles in my hands the others on my back

Perfect and cost effective in a target rich environment

At times I have used the 22 with subs in the morning, then the .223 all afternoon

Then there’s times when the rimfire subs need to do a bit more work…….

Sink one in where the spine meets the skull at the back of the head

I might be a bit cynical but an axis/atlas shot can be a tough shot at longer range at the best of times but a 200m shot to back of head with 22 sub is next level considering a deer generally keeps its head still for about 4 seconds at any time apart from when bedded down. Good on ya.

the round nose thing will help with slower twist and slow speeds... much easier to stabalise...had possum go up tree in front of us while deer stalking today,then hua had cheek to preach at us..... a subby load might have been handy.....

My load is not subsonic but sounds like a 22lr.
8.0gn of blue dot under a 55gn Rusa CMJ projectile.
Gives 1900fps out of a 16" barrel.

Take a look at these for shooting subsonic. Don't see any .224 projectiles for sale but they are shown in the intro.

They look deadly but at $5 each not for me. My .22cal subs will just be used on rabbits and other small game so cheap flat base bullets should do the trick.

Still use and experiment with subs but have settled on mostly using TB @ 7.3grs for about 1911 fps ( Pro Chrony @ 3 m ). Effective killing and still quiet enough that nearby residents don't know I've fired any shots and animals aren't disturbed too much. Without altering 200yd zero this load is near bang on at 50yds. Good enough for what I need. Local range is in yards so that's what I sight in at.

i take it you do make some of these 45grn cast jobbies??? some photos would be good/nice PLEASE.

Lee now do a 224/55gr casting blocks.

Black widow do 224/50gr cast powder coated.
They will send you samples (50) for the cost of postage.
Suggest you email them.
Or to buy 500 for $57au + postage.
